Whether you’re looking for a Primary or Secondary DNS solution, Neustar UltraDNS offers customizable packages to fit any organization’s DNS needs.
Quad9 is a free, recursive DNS service that replaces your ISP's or company's default domain name server (DNS) settings. Quad9 blocks lookups of malicious host names from an up-to-date list of threats when your computer makes any internet transaction that uses the DNS.
This blocking action protects your computer, mobile device, or IoT systems against a variety of risks, including malware, phishing, spyware, C2 command-and-control domains, exploit kit-compromised sites, and botnets. It can also boost performance while ensuring privacy.
Quad9’s service uses threat intelligence from a variety of sources, including:
Quad9 employs DNSSEC, which assures that the results supplied are accurate. It also filters out websites that have been categorized as hazardous using blacklists provided by various security suppliers.
Quad9 supports DNS over TLS (DoT) and DNS over HTTPS (DoH). It’s been increasingly obvious in recent years that standard DNS has significant security flaws due to a lack of encryption. As a result, it is more susceptible to DNS hijacking. Quad9 users are effectively protected from cyber criminals as well as government censorship.
The Quad9 service is run by the Quad9 Foundation, a non-profit organization based in Switzerland whose purpose is to make the internet a safer and more reliable place for everyone.
